More and more studies have demonstrated that bone marrow microenvironment, the fundament of the multiplication and differentiation of hematopoietic stem cells, plays a crucial role in leukemia progression and resistance to treatment. It provides a permissive environment for minimal residual disease and contributes to relapse and multidrug resistance. Mesenchymal stem cells are a kind of important stromal cells in bone marrow niche. In recent researches, MSC have been shown to be one of the major factors modulating the biological features of leukemia cells. The cross-talk between MSC and leukemia cells can take place not only by direct contact, but also by exosome exchange. Exosomes are nano-sized vesicles released by a variety of cells, which contain protein, RNA and mRNA. They are effective tools for transportation between cells, and play an important role in many physiological and pathological processes. Exosome is a new topic in the research of leukemia and microenvironment. The exosome research will help elucidate the mechanism of leukemia, thus providing new ideas for the treatment.

Multiple myeloma(MM) remains incurable with high relapse and chemoresistance rates. Differentially expressed genes(DEGs) between newly diagnosed myeloma and secondary plasma cell leukemia(sPCL) were subjected to a weighted gene co-expression network analysis(WGCNA). Drug resistant myeloma cell lines were established.

Metabolic reprogramming is a hallmark of cancer, crucial for malignant transformation and metastasis. Chronic lymphocytic leukaemia (CLL) and prostate cancer exhibit similar metabolic adaptations, particularly in glucose and lipid metabolism. Understanding this metabolic plasticity is crucial for identifying mechanisms contributing to metastasis.

CD226 plays a vital role in natural killer (NK) cell cytotoxicity, interacting with its ligands CD112 and CD155 to initiate immune synapse formation, primarily through leukocyte function-associated-1 (LFA-1). Our study examined the role of CD226 in NK cell surveillance of acute myeloid leukemia (AML). NK cells in patients with AML had lower expression of CD226.

Hypermethylation of tumor suppressor genes is a hallmark of leukemia. The hypomethylating agent decitabine covalently binds, and degrades DNA (cytosine-5)-methyltransferase 1 (DNMT1). Structural similarities within DNA-binding domains of DNMT1, and the leukemic driver histone-lysine N-methyltransferase 2A (KMT2A) suggest that decitabine might also affect the latter.

Acute myeloid leukemia (AML) is a severe blood cancer with an urgent need for novel therapies for refractory or relapsed patients. Leukocyte-associated immunoglobulin-like receptor 1 (LAIR1), an immune suppressive receptor expressed on immune cells and AML blasts but minimally on hematopoietic stem cells (HSCs), represents a potential therapeutic target. But there has been limited research on therapies targeting LAIR1 for AML and no published reports on LAIR1 antibody-drug conjugate (ADC).
